Application filed July 3,

To all whom it may concern:

Be it known that I, GUs'rAv STROM, a citizen of the United States ofAmerica, residing at Pontiac, in the county of Oakland andState ofMichigan, have-invented certain new and useful Improvements in Apparatusfor Forming Ornamental Facings, of which the following is aspecification, referencebeing had therein to the accompanying drawlngs.p

The invention relates to the manufacture of building blocks and. hasmore, particular reference to the forming of blocks with ornamentalfacings. For instance, it is some times desired to formof cement blocksa structure having the appearance of a brick building. It is thereforean object of the present invention; first, to provide a simple methodfor producing the desired ornamental appearance, and; second, to providea simple construction of apparatus for carrying out the method, as morefully he-reinafter set forth. I

In the drawings: i 1 Figure 1 is a perspective view showing a portion ofa building blockhaving an ornamental face; f t

Figure 2 is a central longitudinal section through the apparatus usedfor producing the ornamental facing; J

Figure 3 is a cross-section thereof; ;Figure is a perspective view of amodified form of apparatus which may be'employed for the same purpose; 7I

Figure 5 is a cross-section through a pors tion of the mold for theblock having the construction shown in Figure 4: applied thereto. I l aIn the manufacture of concrete building blocks it is usual to form thesame in molds in which the material is tamped or pressed and, aftersufiiciently set to retain its shape,

the block is removed from the mold. The outer facing of the block may beformed of material having a different color or appearance from the bodymaterial, but where this facing also has adistinctive structuralappearance, as, for instance, in imitation of brick, special means isrequired for the production of the same. With my improved method Iproduce this appearance by first molding the body of the block, strikingoff the same to form a plane surface and then superposing' upon thissurface material hav- 1922. Serial No. 572,696.

The molding of the body block maybe I accomplished by any suit-ableapparatus which is unnecessary to show ordescribein detail. Preferablythe mold for the block is open at the top and after the body material isfilled therein, thesurplus is removed by striking off, leaving a*planesurface. hen employing the apparatus shown in Figures 2 and 3, thefacing material is deposited upon the struck-off face ofthe block byrolling the apparatusover-such surface, which, as will'be presentlydescribed, will deposit the facing-in the desired structuralarrangement. s

In detail, the apparatus shown in Figures 2 and 3 comprises acylindrical casing A having circular heads B at opposite ends thereofand a central axle C on which said heads are journaled, said axleextending beyond the heads and being provided with handles D fornon-rotative'lyholding the same. The peripheral portion of the casing Ais subdivided by rings E and cross bars F into the outlines of laidbrick and between these'rings andcross bars are open spaces for thedeposit of the facing material. G is a hopper-shaped casing within thecasing A which is non-rotatively supported by the axle C. In the lowerpartof this'casing G is a perforated screen I-I above'which is arrangeda rotary agitatorl, which, when revolved, will cause the sifting of themate rial through the screen. J is a discharge spout below the'soreenywhich extends longitudinally of the casing A andis preferablyrestricted in width to substantially that of the cross bars F. K is ascraper on one side ,of the spout which wipes the innerface of the crossbars F and. rings E during the revolution of the outer casing A. L and Mare intermeshing gears, cthe former mounted uponth'e casing A and. thelatter upon the shaft N. of the rotary agitator I, so that duringtherollingof the casing the agitator is also revolved. O are wedge-shapedparti .tions in the spout J which register with the rings E anddirectthe sifted opposite sides thereofj f WVith the apparatus as ustdescribed, when it is desiredto'face the molded block, the

material upon casing A is rolledover the. surface thereof,

material through i the screen H into. the.

spout J and on to the surface' 'ofthe"molded block- The Surplus ateral;is.,st n 1s fal?y;
